# Installing the dotnet-test Plugin The `dotnet-test` plugin must be loaded before the upgrade can generate a test baseline. Ask whether the user wants to install it. If they decline, treat Test Coverage as **Skip**. {{#if CopilotCli}} Run: ```text copilot plugin marketplace add dotnet/skills copilot plugin install dotnet-test@dotnet-agent-skills ``` Then ask the user to restart the session (`/restart` or relaunch `copilot`) and re-run the upgrade. Do not create test-baseline tasks in the current run because the plugin loads only after restart. {{/if}} {{#if VsCode}} Ask the user to run **Chat: Install Plugin From Source** from the Command Palette and enter: ```text https://github.com/dotnet/skills ``` When VS Code shows the plugins available from that source, ask the user to select `dotnet-test`. Alternatively, add `dotnet/skills` to `chat.plugins.marketplaces`, then ask the user to install `dotnet-test` from the `@agentPlugins` Extensions view. After installation, ask the user to continue the current upgrade. Re-check that `code-testing-generator` is available, then resume planning. {{/if}} {{#if GitHubCopilotApp}} Ask the user to open **Settings → Plugins** or use the **Extensions** menu in the GitHub Copilot App, find the `dotnet-test` plugin from `dotnet/skills`, and install it. Then ask the user to continue the current upgrade. Re-check that `code-testing-generator` is available before resuming planning. {{/if}}
